Hi Lana,

Make sure either that:
1) Your image is in the same directory as your current directory (you
can check what your current directory is by typing 'pwd' (without the
'').  This should be the same directory as your script.
2) You can add the directory path where the image is to Octave's
search path.  If your image is in the directory C:/images for example.
Then using  the command:
before trying to read the image will work as well.

All the rest of the errors you're getting with your script stem from
the fact that your attempt to read the image and save it to the
variable A failed.  Since that wasn't successful, the rest of the code
is trying to do stuff with no data to work with.

Hope this helps,

James Sherman

P.S.  I just noticed that you image name is a bit ... odd.  Are you
sure that your image file has the suffix ".img"?  Usual suffixes are
.jpg, .jpeg, or .png.  I'm not familiar with the .img format, and I
wonder if that might be a typo.
